Stock Lenses
The degree of stock lenses is determined during the process of making lenses, and has a certain universality (that is most people are roughly applicable) range. Optometrists often choose stock lenses as an easy, cost-effective lens option, such as reading glasses or when the wearer needs a quick lens change. Stock lenses are mass-produced rather than individually produced and are great for standard vision correction, but do not provide the same level of performance as personalized precision lenses.

Rx lens is a lens that is completely customized according to the personalized precision lens, according to the wearer's prescription, eye habits, and so on.
Stock lenses can meet the needs of people with visual impairments in daily life situations. However, a "perfectly tailored" pair of glasses can offer more advantages. The stock lenses accommodate the visual point of each eye, but neither the frame nor the actual fit of the lenses are taken into account during fit. In lens production, Rx lenses take more into account the wearer's visual effects generated by the frame, and the manufactured lenses are more precise, while ensuring that the wearer enjoys the best natural vision.
Ideally, a perfect harmony between frames, lenses, individual visual needs and the shape of the wearer's face is required to achieve comfortable and natural vision, especially for people with presbyopia or uncommon visual defects. Freeform technology provides the lens wearer with a wealth of personal data and, thanks to complex mathematical calculations, produces lenses that are precisely manufactured and fit the wearer, allowing the wearer to have the best vision through the chosen frame. This is clear vision with the widest possible field of view at different distances and with excellent wearer tolerance. The more complex and unique the situation, the more dramatic the difference between custom and stock lenses.
